Oxide-ion and proton conducting electrolyte materials for clean energy applications: structural and mechanistic features
No full textThis critical review presents an overview of the various classes of oxide materials exhibiting fast oxide-ion or proton conductivity for use as solid electrolytes in clean energy applications such as solid oxide fuel cells. Emphasis is placed on the relationship between structural and mechanistic features of the crystalline materials and their ion conduction properties. After describing well-established classes such as fluorite- and perovskite-based oxides, new materials and structure-types are presented. These include a variety of molybdate, gallate, apatite silicate/germanate and niobate systems, many of which contain flexible structural networks, and exhibit different defect properties and transport mechanisms to the conventional materials. It is concluded that the rich chemistry of these important systems provides diverse possibilities for developing superior ionic conductors for use as solid electrolytes in fuel cells and related applications. In most cases, a greater atomic-level understanding of the structures, defects and conduction mechanisms is achieved through a combination of experimental and computational technique

Functional niche differentiation in co-occurring congeneric plants / by Md Saiful Islam Khan.
No full text"Niche differentiation is argued as one of the mechanisms explaining species coexistence. Despite their sessile nature, similar resource needs and traits to acquire and utilize resources closely related plant species coexist. I hypothesized that i) spatial distribution of congeneric species would be similar because they are closely related with similar traits and resource needs and ii) each species will perform different biological functions (growth vs. reproduction) optimally at different points along a resource gradient and thereby differentiate their functional niche to ensure coexistence by complementary resource use. I collected data on two congeneric wild blueberry species, Vaccinium angustifolium and V. myrtilloides on occurrence from 13,500 20 x 20 cm quadrates, their growth and reproductive response to light and microhabitat parameters from 360 1 x 1 m quadrates along 90 30 m transects from 5 regions of NW Ontario [Northwestern Ontario]. I also grew these two species in a common garden experiment (CGE) under a shade gradient to test their response to light in competition-free environment. A chi-square test confirmed that V. angustifolium and V. myrtilloides are co-occurring species. Variance partitioning analysis revealed that light is the most important microsite variable. Frequency of occurrence showed their abundance gradually increase from low to high light with high niche overlaps. Regression model fitting of cover (indicating growth) and berry yield (indicating reproduction) along the light gradient provided species functional response curves
Nonlinear dynamic behaviour of fully coupled Spar platform /A.B.M. Saiful Islam
Get PDFThe offshore industry has moved towards deep water regions due to continuous depletion of oil and gas reserves at shallow to intermediate water depths. Conventional fixed jacket and bottom supported compliant platforms are inefficient for deep water exploration. Attention has therefore shifted to floating production systems. Floating Spar is one of the concepts amongst the floating structure categories. Spar platform is an assemblage of mooring, riser and Spar hull responding in a complex way to aerodynamic and hydrodynamic forces. At deep water, mooring lines/risers contribute significant inertia and damping. Associated nonlinearities compound the problem further. Precise motion investigation of platform is required for integrity and associated costs of Spar hull and mooring lines/risers. Proper dynamics cannot be assessed by conventionally used decoupled quasi-static methods which ignore all or part of the mooring/riser-platform interaction effects. Coupled analysis can capture all the complexities in reliable fashion. Hence, coupled behaviour of Spar Platform under wave, current and wind loading is of great interest. Suitability of Spar platform in Malaysian deep sea and coupled effect of riser deserve essential concern.
In the present study, fully coupled integrated Spar-mooring system (NONLIN-COUPLE6D) has been modelled. Using a nonlinear finite element approach, the deep draft Spar (DDS) hull and each catenary mooring line (CML) are simulated in a single assemblage. Spar hull is treated as rigid beam element and CML as hybrid beam element. The mooring lines as an integral part of the system support the spar hull at fairlead and pinned at the far end on the seabed. They partly hang and partly lying on the sea bed. Sea bed is modelled as a large flat surface with a provision to simulate mooring contact behaviour. Mooring line dynamics considers the instantaneous tension fluctuation and damping forces with time-dependent variance of other properties. Essential nonlinearities involved in the system are properly captured. As all the forces on Spar and CMLs act simultaneously, coupled action is achieved. Hence, there is no need of iteratively matching the force, displacement, velocity and acceleration at the fairlead position. The commercial finite element code ABAQUS/ AQUA is found to be suitable for the present study. The selected configuration of coupled Spar platform is analysed under regular wave, severe wave, current force, wind loading as well as Malaysian environment. For moderate wave, Stroke’s 5th order wave theory is chosen, whereas for other cases wave kinematics are computed by Airy’s wave theory. The API RP 2A and Emil Simiu spectrum have been considered for wind forces. Wave and wind characteristics of Malaysian sea are simulated for 100-year storm condition. Effect of sea bed friction is evaluated under Malaysian environment. Stable response analysis is performed by bifurcation technique and Mathieu instability. Integrated Spar-mooring
Synthesis, Characterization and Antibacterial Activity on Dinuclear Schiff-base Macrocyclic Metal Complexes
No full textSchiff-bases and their dinuclear metal complexes have been extensively received special attention because of their wide range of applications including catalysts, medicine crystal engineering, anti-corrosion agent, and biological activities [1]. Dinuclear macrocyclic lead (II) complex, Pb2L1(SCN)4 was synthesized by template condensation of pyridine-2,6-dicarboxaldehyde and 1,2-bis (2-aminoethoxy) ethane in presence of Pb(SCN)2 as the metal source, here L1 is tetra-Schiff-base macrocycle. Transmetallation treatment of Pb2L1(SCN)4 with Co(PF6)2.6H2O produced the new complex, Co2L1(SCN)4 [2]. Reduction of lead (II) complex gave new reduced tetra-Schiff-base macrocyclic ligand, L2[3]. All the metal complexes and ligand were characterized by UV-Visible, FT-IR, 1H NMR spectroscopy. The antibacterial activities against some pathogenic gram positive and gram negative bacteria were studied by cylinder disk diffusion method. The complexes were found to inhibit the growth of bacteria
From single-cell transcriptomics to single-molecule counting
No full textRNA-sequencing (RNA-seq) technology has been progressing so fast in the last few years and made it possible to perform transcriptome analysis at single-cell level that was even unimaginable a few years before. Nowadays, the importance of gene expression analysis at the single-cell level is increasingly appreciated for the study of complex heterogeneous tissue. Also, in order to solve the obscure and no consensus definition of cell types, the single-cell gene expression analysis approach will be important. In this thesis we described a novel approach of single-cell gene expression profiling, called Single-cell Tagged Reverse Transcription (STRT). Here we can analyse 96 single cells at the same time by using a DNA barcode to tag individual single-cell. We analysed both 41 embryonic stem cells (ES) and 44 mouse embryonic fibroblast (MEF) cells in a 96-well PCR plate using STRT and successfully separated the distinct cell types from each other by cluster analysis using only the gene expression profile. We believe that the strategy to discriminate cell types using gene expression profiling will empower the unbiased discovery and analysis of heterogeneous cell populations in both normal and diseases tissue. However, the low efficiency of cDNA synthesis (~ 10%) and PCR amplification bias of this first STRT version reduced throughput and also decreased the possibility to detect genes that were expressed at lower level.To improve the efficiency of cDNA synthesis, we significantly improved the template switching (TS) mechanism – the mechanism to make secondary oligonucleotide from RNA during first strand cDNA synthesis. Since most of the present single-cell methods use TS mechanism, the base preference of terminal transferase activity was studied in detail. We found that an NGG motif at the 3 ́ end of the template switching oligonucleotide (TSO) will work better than a GGG motif.To remove the amplification bias we introduced a molecular barcode, a 5 bp short random degenerate sequence, which entirely eliminate the amplification bias. As this short random sequence uniquely labels each single molecule, their exact number can be determined. By introducing a microfluidic sample preparation, Fluidigm C1, we ensure the quality of cells that undergo sample processing until sequencing. In this updated method, called STRT-C1, we used 96 ES cells and split it as two final libraries consisting of one single strand cDNA library and one double strand cDNA obtained by amplifying the first single strand cDNA. We also used and analysed spike-in RNA in the same experiment. Both the reproducibility (correlation coefficient >99.5 within and between sample) and efficiency of reverse transcription (~48%, 5 folds more than previous version of STRT) of the improved method are excellent. Correlation coefficient for the endogenous gene within and between samples is much better at the molecule level than at the read level, especially for the genes of low abundance.By analysing only the spike-in RNAs, we found that technical noise is minimized and we can observe true biological noise for endogenous genes. Some biological noise is intrinsic at the single-cell level but most of the genes showed only low level of noise. However, we detected ~173 genes in ES cells which shows significant noise. Our data also revealed that biologically noisy genes have a significant function to give a resonant state of the embryonic stem cell.In conclusion, the single-cell molecule counting method makes it possible to count molecules in single- cell accurately and without any bias. So we believe our STRT-C1 version of the single-cell method is a significant step forward for all expression analysis.List of scientific papersI.
